CURTAIN-HAN GER CLAMP.

Specification of Letters Patent.

Patented Feb. 3, 1914.

Application filed November 4, 1912. Serial No. 729,393.

To all whom it may concern:

Be. it known that I, N ILS EMIL LARSON, a citizen of Sweden, andresident of the borough of Manhattan, in the county of New York andState of New York, have invented certain new and useful Improvements inCurtain-Hanger Clamps, of which the following is a specification.

This invention relates particularly to hangers for positively holding acurtain by clamping without any pins or other adjuncts passing throughthe same.

One of the objects of the invention is the production of a simple,eflicient and durable hanger which will clamp a curtain between its jawswithout injury to the most delicate fabric.

Another object is to provide a curtain hanger having a difierentialmovement for clamping curtains or draperies of various thicknessesbetween its jaws.

A further object is to provide a curtain hanger adapted to slide eitheron a rod or Th between a pair of pole members.

Other objects and advantages will become apparent as the descriptionproceeds.

lVith the aforesaid objects in View, the invention comprises theimprovements and combinations of parts hereinafter described in theirpreferred embodiments as illustrated in the accompanying drawings, andpointed out in the appended claims.

In the said drawings ;Figure 1 is a top plan view of the curtain hangerclamp; Fig. 2 is a front view of Fig. 1; Fig. 3 is a section on the line3-3 of Fig. 2 and Fig. 4 is a section on the line 44 of Fig. 8.

In these views the numeral 5 designates a head or loop of spheroidalshape and having a pair of integrally formed jaws 6, 7 extendingtherefrom. These jaws consist each of a fiat portion and an undulatedportion as shown at 8, 9 so that they may have a firmer hold or strongergrip on the curtain. The inner faces of the jaws which are smooth havetheir undulated portions 8, 9 corrugated in gradual curves so as not toinjure or impart a permanent set to the fibers of the material clampedbetween them. The said jaws 6, 7 are stiffened by having their edgesprovided with right angular flanges 10, 11 which are continuous all theway from one side around the head 5 to the other side. The fiat portionsof the jaws below the head 5 constitute together with the flanges 10, 11outwardly facing recesses 24, 25. Where these flanges pass around thesaid head 5 they are laid or folded down inwardly thereupon as indicatedat 12, 13 by virtue of which the resiliency of the said head is notimpaired.

A pair of links 14, 15 pass transversely through suitable apertures inthe jaws 6, 7 at a specified distance below the head or loop 5. Levers16, 17 having integrally formed trunnions 18, 19 journaled in the outerends of the said links 14, 15, are provided with right angularly offsetcam or nose portions 20, 21 that bear oppositely against the jaws 6, 7betweenthe flanges 10, 11. The said levers 16, 17 lodge in thehereinbefore mentioned recesses 24, 25 when swung into their clampingpositions. In this way the jaws are brought up toward each other toclamp a curtain or draperies between them. The inherent resiliency ofthe loop 5 normally tends to spread the jaws apart. e maximum opening ormovement of the jaws is obtained when both levers are horizontal. Thecams may be of unequal length. As shown the cam 20 at the left issomewhat longer than the cam 21 at the right hand side, by virtue ofwhich the jaws will move to a greater or less degree depending uponwhich lever is operated. This is particularly useful when inserting verythin curtains or shades between the jaws in which case both leversshould be turned up to bring the jaws close together. For a heavy orthick curtain both levers should be swung down to receive it, afterwhich either one of them may be brought back into its upward positionleaving the jaws the proper distance apart to hold the curtain. In thisway undue straining of the holder clamp is avoided, besides it protectsthe curtain from too much pressure. It will be noticed that the majorpart of the lever travels past its vertical center. This obviates thetendency of the lever to spring back. The upper part of the lever iscurved so that it fits snugly in under the spheroidal head 5.

As shown by the dash-and-dot line at A the holder clamp may slide upon arod or it may be moved between a pair of pole members one of which isindicated at B. The position of the curtain between the jaws is shown bythe dash-and-dot lines at C.

While a certain preferred form of this ourtain holder clamp has beendescribed, it will be understood that numerous changes can be madetherein without departing from the invention.

Having described my invention, what I desire to secure by Letters Patentand claim is 1. A curtain hanger clamp comprising a head, a pair of jawsextending therefrom provided with lateral flanges forming outwardlydisposed recesses, and means operating differentially on said jawswhereby open ings of various widths are obtained therebetween, saidmeans lodging in said recesses when in their clamping positions.

2. A curtain hanger clamp comprising a looped portion, jaws formedtherewith having flanges projecting outwardly from their opposite edges,and operating levers connected with said jaws on opposite sides, wherebythe aws can be partly closed from either side, said levers being lodgedout of the way between said flanges when in clamping position.

3. A curtain hanger clamp, comprising a head, a pair of jaws extendingtherefrom consisting each of a flat portion and a corrugated portion,flanges following the edges of said jaws, and curved levers foroperating the jaws located on the flat portions thereof, said leverslodging between the flanges under said head, and having outwardly turnedportions whereby they can be pulled out.

pair of outwardly flanged jaws joined at one end and having suitableapertures adjacent to their flanges, a pair of loose llnks passingthrough the apertures and cam levers pivoted to opposite ends of saidlink adapted each to moi e the jaws a different distance.

6. A curtain hanger clamp comprising a looped head, jaws extendingtherefrom having flanged edges, links passing through said jaws adjacentto their flanges, and cam levers hinged at opposite ends of said linksadapted each to move the jaws a diiferent part of the opening'betweenthem, said levers being arranged to swing up entirely under the headbetween said flanges when in clamping position.

Signed in the borough of Manhattan in the county of New York and Stateof New York this th day of October A. D. 1912.
